To all whom t may concern.'

V Be it known that I, HARRY P. FAiRoHILD, a citizen of the United States, residing at 412 West End avenue, New York, county of NewYork, and State of New York,have

l erence-to the annexed drawing, in which- Figure l shows the pen closed and adapted to be carried in the pocket or carried as a charm, for which purpose a ring is provided upon the cap; Fig. 2 shows the pen extended and the cap removed and applied to the end of the extension-tube; Fig. 3'

. shows the body of the pen with the extension-tube in section and drawn out to the farthest limit; Fig. t shows the shell separate fromJ the body; Fig. 5 is a l'side view of the lining for the extension-tube; Fig. 6 is an elevation of the plug for the outer end of the extension-tube; and Fig. 7 is a j longitudinal sectionof the pen-cap. Fig. 8

is a section online 8-8 in Fig. 3.

In the drawing, a designates the composition body of the pen having nozzle b to carry the pen o, and shown'provided with arshort section of screw-thread d to retain the cap thereon. The shell e is pressed tightly upon the body as shown in Fig. 8, and provided with outer end.

The usual' composition cap is shown in Fig. 7 with a metal coveringv It having a rmg 27 upon itsY outer end. The cap is Aformed with a socket tfat its open end to closely t the nozzle b, and with an internal thread g to screw upon the thread d, as usual.

The extension-member consists of the tube 7c having a lining Z which' is slotted from one end at m'for the greater partI of the lateral stud f at its its length, to t uponthe stud. f. Such lining is litted to slide smoothly upon the shell e with the stud in the slotm, the stud thus limiting the outward movement of theextension tube and preventingits rotation upon thebody.

' To retain the lining securely in the shell, the extension-tube has a shoulder k at its inner end fitted to one end of the lining, and at the opposite endthe tube is closed by a plug n which is made of suitable size to fit the open socket la. of the cap. The

plug is not inserted in the outer end of the tube untilv the llatter 'with its lining is slipped upon the shell e from the direction of the pen 0. The plug ln, has a collar n fitted to the bore of the tube, and when the ltube is thus slipped upon the body, asshown in Fig. 3, the collar is inserted in the tube and locked therein by turning a ilange o upon the 'end of the tube. The. collar-may also be secured to the tube by solder, ifdesired. The construction thus provides for the convenient assembling of the parts and 'A 80 permanently in working condi- A,

the securing of them together so as to retain them tion.

.The tube k serves as a cover t0 support and strengthen the slotted lining l which its' tightly therein, and is held therein by the iange lc and the collar upon theplug n. The plug prevents the extension-tube from sliding too far upon the shell or body of the pen. l

This invention furnishes a convenient and effective means of converting an ordinary fountain pen into an extension pen,'and thusA produces an article short enough to carry in the pocket, whileat the same time constructed for extension to aconvenient length for use in writing. l 'v l Having thus set forth the nature of the invention what is claimed herein is:

1. An extension fountain pen having a. hardened composition body, a metallic shell pressed tightly upon the body and having a.

lateral stud at its outer end, an extension in contact with the flange k' and having aA slot to engage the lateral stud, and the outer end of the extension tube having .a plug se cured in the tube to retain the lining therein.

Q memes 2. An extension fountain pen having a engage the lateral stud, and the outer end l@ hardened composition body, Aa metallic shell ofthe extension tube having a flanged plug pressed tightly upon the body and `having a with a collar fitted inside the extension tube lateral stud at its Vouter end, an Aextension and a'ange turned overv such collarupon 5 tube provided with ange lc at its inner end the end of such tube, the collar serving toadapted to slide upon the shell, a lining retain the liningwithin the extension tube. 15' E l itted Withinthe extension 'tube' and adapted In testimony whereof I have hereunto Set 'i H! to slide upon the shell and having one end my hand.v j Contact with the flange le and a slot to A HARRY?.
